What size would work better an 17x9" wheel?? 275/40 or 255/40?? I want 275, but if it is going to handle funny I had rather just run the narrower tire.

 

In street tires, 275's are usually too big for 9" wheels. However, you might be able to fir some track tires on there that size but I would probably opt for the 255's to start out with.

 

BTW, where did you find V710's in 255's? I don't remember seeing those in 255's (so I was going to go Victoracers for that reason).

 

No 17" 255's that I see here:

I just guessed I thought they came in 255 but I guess I was thinking of victoracers, and most tires seem to jump from 255-275, but I guess V710 go from 245-275. I'm going to go 275, since I can't get 255's. I really want something wider than 245s.

Also Tirerack has the wheel range on 275s from something like 9"-11", I just feel 275s will kinda crammed on a 9" wheel but hey alot of the miata around people 225's on a 14x6" wheel.

 

275's are fine for 9 inch wheels. firebirds/camaros come that size from factory if you get ws6 or SS package. i drove on them on street for years. and i used 275 kumho's v700 on that size wheel in autocross and open track for years and they were perfect. you will have no issues.
i'll be ordering v710's soon for this coming season, 245-45-17 and 275-40-17 for my staggered 8.5 and 9.5's.

 

Thanks thats what I was looking for and that is basically the sizes I planned on running.

 

Chris, you don't need any stinkin' R compound tires, get you a set of "RoadHandlers". R compond tires are just a crutch for those that cant drive

 

HA HA!!! I gotta beat those pesky TC/SC miatas that make as much power as me and have about 20+yrs of experience on me, thats hard to do even on R compounds.
